I think it's natural for fans to project what a player might be like, or the role they might play when they get here....since they haven't seen that yet, a player comparison is one way to paint that picture.This! We know the staff wants Josh so let's get him committed to Iowa. Which former player Josh most resembles is not important.
Kohler for instance....has a game that resembles Garza's in a lot of ways....not exactly the same...Kohler has a turn around fade away shot that Garza rarely displayed....and Garza is bigger....but it gives you an idea of what he plays like.
